In the trials, conducted at the International Center for Tropical Agriculture (CIAT) in Colombia, multiple rice lines carrying the nitrogen use efficiency (NUE), water use efficiency (WUE) and salinity tolerance (ST) traits outperformed appropriate control lines by an average of 25 percent under limiting nitrogen applications, when measured for yield, with the lead line yielding up to 33 percent more.

The same lines yielded an average of 40 percent more than controls under combined limiting nitrogen and drought conditions in the field, with the lead line showing 50 percent higher yield under multiple abiotic stresses.

Previous field trials in California by Arcadia had shown the potential for stacking these traits in rice as a tool to safeguard food security, and the recent data from CIAT confirms that there may be synergistic effects between traits that protect crops against various abiotic stresses.

“Arcadia is a recognized leader in the area of abiotic stress mitigation traits targeting meaningful yield gains in the most important crops in the world,” said Raj Ketkar, president and CEO. “These results show that our agricultural productivity traits hold significant promise to help farmers globally as they deal with the effects of a variety of challenging growing conditions, such as nutrient-deficient soil, drought and salinity, enabling them to increase yields and improve farm revenue.”

Rice is the world’s most valuable crop, with an annual harvest value of around $340 billion. Americans eat an average of 26 pounds of rice annually, while Asians consume 300 pounds per year per capita. Global rice production in 2017 was 837.3 million tons, grown on 399 million acres worldwide, roughly equivalent to the surface area of Iran, the 17th largest country in the world.

The triple-stack trait trials in rice are part of the NEWEST project, coordinated by the African Agricultural Technology Foundation (AATF), and sponsored by the Feed the Future initiative of USAID. AATF recently secured continued funding for performing regulatory field trials with NUE rice in Africa.

The International Center for Tropical Agriculture (CIAT) – a CGIAR Research Center – develops technologies, innovative methods, and new knowledge that better enable farmers, especially smallholders, to make agriculture eco-efficient – that is, competitive and profitable as well as sustainable and resilient. Eco-efficient agriculture reduces hunger and poverty, improves human nutrition, and offers solutions to environmental degradation and climate change in the tropics. With headquarters near Cali, Colombia, CIAT conducts research for development in tropical regions of Africa, Asia, and Latin America. www.ciat.cgiar.org.

The African Agricultural Technology Foundation (AATF) is a not-for-profit organization that facilitates and promotes public/private partnerships to access, develop, adapt and deliver appropriate agricultural technologies for sustainable use by smallholder farmers in Sub-Saharan Africa through innovative partnerships and effective stewardship along the entire value chain. It is headquartered in Nairobi, and its mandate covers sub-Saharan Africa. For more information, visit www.aatf-africa.org.
